Multiple "Multiplayer Event System" on scene darkens UI

Hello everyone!

I’ve been messing around with the Input System Multiplayer features to manage a local multiplayer game I’m making.

I’ve been having this issue in which if there are multiple “Multiplayer Event System” in scene, they darken every UI in the scene additively. If I dissable on or more “Multiplayer Event System” the UI goes back to normal.

Here is a video of said issue:

I couldn’t find anything on this issue, my thought is that it has to do with the “First Selected” field:

If anyone has any idea of what could be happening, I would gladly appreciate the help.

PS: I’m using Unity version 2022.1.7f1 URP in the video. I created another small project, to test this, in version 2021.3.6f1 URP and the same happens over there too

UPDATE: I found out that the Multiplayer Event System generates a Canvas Group in the World Space canvas of each player. If I disable the canvas group, that darkening goes away.
I haven’t found a fix yet, just wanted to update.

UPDATE 2: Issue is being tracked by Unity, but there is no fix yet → Unity Issue Tracker - Colors of buttons change when using multiple Multiplayer Event Systems

UPDATE 3: Issue fixed in a no yet released version of the Input System Package → InputSystem/Packages/com.unity.inputsystem/CHANGELOG.md at develop · Unity-Technologies/InputSystem · GitHub
